System for indicating the grade of an abrasive

Abstract

A system for indicating the nature of an abrasive surface that is determined by an abrasive with a regular pattern, at least a basic portion of which is repeated, which system comprises at least two different abrasive elements that each have an abrasive surface, wherein the basic portion of the pattern of the one abrasive surface has different dimensions to the basic portion of the pattern of the other abrasive surface.

1 . System for indicating the nature of an abrasive surface ( 1 ) that is determined by an abrasive with a regular pattern ( 2 ), at least a basic portion of which is repeated, which system comprises at least two different abrasive elements that each have an abrasive surface ( 1 ), wherein the basic portion ( 3 - 5 ) of the pattern ( 2 ) of the one abrasive surface ( 1 ) has different dimensions to the basic portion ( 3 - 5 ) of the pattern ( 2 ) of the other abrasive surface ( 1 ). 
   
   
       2 . System according to  claim 1 , wherein the basic portions ( 3 - 5 ) of the abrasive surface ( 1 ) of the abrasive elements are uniform. 
   
   
       3 . System according to  claim 1 , wherein size of the basic portions ( 3 - 5 ) is a guide to the grade of the abrasive. 
   
   
       4 . System according to  claim 3 , wherein a coarser grade is associated with a larger size of the basic portion ( 3 - 5 ). 
   
   
       5 . System according to  claim 1 , wherein the basic portion ( 3 - 5 ) of each pattern ( 2 ) comprises a diamond shape. 
   
   
       6 . System according to  claim 5 , wherein the diamond shape is the side view of a polished diamond ( 3 ,  4 ). 
   
   
       7 . System according to  claim 6 , wherein the diamond shapes ( 3 ,  4 ) in side view alternate with the point thereof pointing in opposing directions. 
   
   
       8 . System according to  claim 5 , wherein the diamond shape ( 5 ) comprises the top view of a polished diamond. 
   
   
       9 . System according to  claim 1 , wherein the abrasive comprises diamond particles. 
   
   
       10 . System according to  claim 1 , wherein the abrasive comprises cubic boron nitride. 
   
   
       11 . System according to  claim 2 , wherein size of the basic portions ( 3 - 5 ) is a guide to the grade of the abrasive. 
   
   
       12 . System according to  claim 2 , wherein the basic portion ( 3 - 5 ) of each pattern ( 2 ) comprises a diamond shape. 
   
   
       13 . System according to  claim 3 , wherein the basic portion ( 3 - 5 ) of each pattern ( 2 ) comprises a diamond shape. 
   
   
       14 . System according to  claim 6 , wherein the diamond shape ( 5 ) comprises the top view of a polished diamond. 
   
   
       15 . System according to  claim 7 , wherein the diamond shape ( 5 ) comprises the top view of a polished diamond.
